Hi there,

I'm just looking for an expression function that I could use to get an object's global scale. I'd like to use it to detect if parts of my rig have been mirrored.

Any ideas?
Thanks!
Pete

You can use Python to get the value of the scales using evalParmTuple.

Something like this:

spam = hou.node("path/to/object/you/want/to/get/the/scale")

egg = spam.evalParmTuple("s")

print egg

# (-1.0, -1.0, -1.0)

Hey thanks huey_yeng! I was looking for an expression function though so I could put it into a channel.



Is that a case where I'd maybe switch this to python? (I've never actually done that).

Yeap you can switch that to Python for Python expression.

If I'm not mistaken, Houdini will colour code the parameter with purple if the expression it is expecting was invalid.

You can also toggle the expression type anytime by right clicking it and go to Expression > Change Language to whatever.
